  • a contact portion of the return lever is configured to contact the brake member and said contact portion is formed with an arcuate shape.
  • the bail arm is reversed to the line releasing position upon casting or thumbing. Also, when the feeding of the fishing line is stopped or the fishing line is wound, the bail arm is returned back to the line winding position. When it is reversed to the line winding position and the rotor is rotated, the fishing line is guided by and wound around the spool. On the other, when the bail arm is in the line releasing position, the rotor is braked by the rotor brake mechanism. Accordingly, there is no fear that the rotor is rotated accidentally. In addition, since the brake mechanism just brakes the rotor but does not lock the rotor, it is possible to readily rotate the rotor if the rotor is manually rotated.
  • the return lever is a part of a bail reversing mechanism and is also part a rotor braking mechanism thus reducing the number of moving parts and simplifying manufacturing costs.
  • the rotor brake mechanism just brakes the rotor but does not lock the rotor in place, since with additional force it is still possible to rotate the rotor against the braking force. For this reason, once the rotor is set at a suitable rotational phase upon casting or thumbing, it is possible to keep the phase and to readily rotate the rotor from the set phase to another phase. It is also possible to adjust the rotational phase of the rotor as desired.

  • the projection 50 c is positioned as shown in solid lines in FIG. 9, where the bail arm is in a line releasing position, and further the projection 50 c located in the vicinity of the projection 42 a , the projection 50 c is spaced apart from the braking member 55 a.
  • the brake member 55 a is endless in the Second Embodiment, it is possible to use an elastic member available on the market such as an O-ring. Also, when the rotor 3 is rotated under the condition that the bail arm 25 is kept in the line releasing position, since the projection 50 c is separated away from the brake member 55 a in the vicinity of the switching projection 42 a so that the brake is released, the rotation of the rotor 3 is light and the second toggle spring mechanism 41 may readily be moved from the second position to the first position.
  • a D-shaped groove for mounting the O-ring may be formed in the wall surface 2 d and the O-ring may be fixed by a suitable fixing means such as an adhesive.
  • the first bail support member 30 ′ is pivotally mounted outside of the first arm portion 21 .
  • the first rod 45 of the first toggle spring mechanism 40 of the bail reversing mechanism 26 is bent at its tip end radially outwardly and is engaged with the first bail support member 30 ′.
  • the other structure of the first toggle spring mechanism 40 is the same as that of the above-described First Embodiment.
  • the second toggle spring mechanism 41 has a return lever 50 , a second sleeve-like member 51 a retained to the return lever 50 ′ at one end, a second rod 52 a which is received at one end in the second sleeve-like member 51 a and pivotally mounted at the other end to the rotor 3 , and a second spring 53 for biasing the second sleeve-like member 51 a on the side of the return lever 50 .
  • the return lever 50 ′ is pivotally mounted within a plane in parallel with the rotor rotational plane to a rear surface of the joint portion between the cylindrical portion 20 of the rotor 3 and the first arm portion 21 .
  • the return lever 50 ′ has a retainer cutaway 50 a ′ for retaining the rear end of the first sleeve-like member 46 of the first toggle spring mechanism 40 , a hole 50 b for retaining the second sleeve-like member, and a projection 50 c that extends toward the rotor rotational center axis.
  • a gap is defined between the surfaces of the retainer cutaway 50 a and the rear portion of the first sleeve-like member 46 to allow for a collision sound to be produced upon relative movement therebetween.
  • a brake member 55 b is composed of the O-ring, and is mounted on a bottom portion of the annular recess 2 c unlike the above-described two embodiments. For this reason, as shown in FIG. 12, the tip end portion of the projection 50 c is brought into contact with the outer circumferential portion of the brake member 55 b rather than the side portion thereof. As shown in FIG. 11, the tip end portion of the projection 50 c is formed into an arcuate shape about the swing center of the return lever 50 . Therefore, when the projection 50 c contacts the brake member 55 b , the projection 50 c is moving in a direction that is substantially tangential to the circumference of the brake member 55 b . As seen in FIG.
  • the brake member 55 b then becomes compressed in the radial direction of the circumference of the brake member 55 b .
  • the direction in which the projection 50 c is moving when the projection 50 c contacts the brake member 55 b is substantially perpendicular to the direction in which the brake member 55 b is compressed.
  • the projection 50 c is thus formed on the arcuate shape, so that, even if the return lever 50 is swung to some extent by the displacement when the rotor 3 is rotated upon the braking, the projection 50 c always enters by the same amount from the outer circumferential side into the brake member 55 .
  • the contact condition hardly changes. For this reason, even if the rotor 3 is manually rotated, the brake force hardly changes so that a stable brake force can be obtained.
  • the return lever 50 ′ may take the first position indicated by the two-dot and dash line and the second position indicated by the solid line in FIG. 11 with the second sleeve-like member 51 a and the second spring 53 applying force to assist in the toggling thereof.
  • the first position corresponds to the first position of the first toggle spring mechanism 40 and the line winding position of the bail arm 25
  • the second position corresponds to the second position of the first toggle spring mechanism 40 and the line releasing position of the bail arm 25 .
  • the switching projection 42 b is formed in the wall portion of the annular recess 2 c of the body 2 a on the outer circumferential side of the brake member 55 b and the brake member 55 b may be arranged substantially in an annular shape.
  • An operating shaft 8 a of the operating lever 8 is cut away into a triangular shape at a position where the brake member 55 b passes as shown in FIG. 11 in order to avoid the brake member 55 b composed of the O-ring.
  • the arrangements of the bail reversing mechanism and the rotor brake mechanism are not limited to those of the above-described embodiments. It is possible to provide the rotor brake mechanism separately from the bail reversing mechanism. For instance, as shown in FIG. 13, a cooperating mechanism 60 composed of a toggle spring mechanism and a lever member 61 operated by the cooperating mechanism 60 are provided on the second arm portion 22 of the rotor 3 .
  • the O-ring is used as the brake member in the foregoing embodiments but the cross-section of the brake member is not limited to a circular shape like the O-ring.
  • the positional relationship between the first rod 45 and the first sleeve-like member 46 in the first toggle spring mechanism 40 may be the opposite positional relationship as shown in the second toggle spring mechanism 41 of the third embodiment, i.e, the arrangement in which the first sleeve-like member 46 is engaged with the first bail support member 30 .
  • the return lever is operated by the toggle spring mechanism in the foregoing embodiments.
  • the return lever as one example of the moving mechanism operate independently of the toggle spring mechanism.
  • the operation mode of the return lever is not limited to the swing motion. It is possible to use any operational mode if it is structured that the return lever moves in cooperation of the swing motion of the bail arm as disclosed in the above-described publication.
  • the rotor if the bail arm is brought in the line releasing position, the rotor is braked. Accordingly, there is no fear that the rotor is rotated accidentally. In addition, since the rotor is braked but is not locked, it is possible to readily rotate the rotor manually using extra force to overcome the braking. For this reason, if the rotor is once set at an optimum rotational phase upon casting or thumbing, it is possible to maintain its phase and also to readily rotate the rotor from the set phase to another phase, and thus the rotational phase (or position) of the rotor can be adjusted as desired.
